BACKGROUND Males and females exhibit different susceptibility to allergic diseases. OBJECTIVES The aim of the study was to evaluate gender-related differences in the prevalence of allergic diseases in Poland. MATERIAL AND METHODS To evaluate this problem, data from the Polish Multicenter Study of the Epidemiology of Allergic Diseases (PMSEAD) was analyzed. There were assessed 16,238 individ...

BACKGROUND Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI), a common preservative in some brands of moist toilet paper (baby wipes and moist towelettes), has been reported to be a cause of allergic contact dermatitis. However, few cases have been reported in the United States. OBSERVATIONS We report the cases of 4 adult patients with severe perianal and perineal allergic contact de...

After more than a decade of use, topical minoxidil solution has proven to be a safe and effective treatment for androgenetic alopecia. However, some patients present with complaints of pruritus and scaling of the scalp. The most common causes of these symptoms include irritant contact dermatitis, allergic contact dermatitis, or an exacerbation of seborrheic dermatitis. Patients suffering from a...

Lymphomatoid contact dermatitis is a pseudolymphoma with clinical and histological features of allergic contact dermatitis and cutaneous T cell lymphoma. Incorrect diagnosis may lead to unnecessary testing, unnecessary treatment, or patient harm. The objective of this study is to present a case to demonstrate the diagnostic challenge and overlap between allergic contact dermatitis and cutaneous...

Some medicinal plants, which are known to produce allergic reactions, are also specifically used as antiinflammatory agents. Among the more relevant plants, we report species with cinnamaldehyde, cinnamic alcohol, geraniol, hydroxycitronellal, eugenol and isoeugenol are all potential allergens. In addition, fragrances, which are mixtures of small-molecular-weight compounds, may induce allergic ...

Background Allergic contact dermatitis (ACD) is often under-recognized in the pediatric population. In the first years of life ACD it is often confused with other types of dermatitis, such as irritant dermatitis or atopic eczema (AE). In the last two decades an increase in ACD in children and adolescents was observed, reaching similar frequencies to those seen in adults (20-70%). ACD acquired i...

Chemical pruritogens and algogens evoke primarily itch and pain, respectively, when administered to the skin of healthy human subjects. However, the dominant sensory quality elicited by an algesic chemical stimulus may change in patients with chronic itch where bradykinin, elicits itch in addition to pain. Here we tested whether normally pruritic and algesic chemicals evoked abnormal itch- or p...

“Dermatitis, eczematous, and allergic disorders, followed by skin infections and infestations, and pigmentary disorders are the commonest skin disorder groups. Contact dermatitis (allergic and irritant), followed by hyper pigmentations, acne, viral infections, atopic dermatitis, and parasitic infestations topped the list of the most prevalent skin disorders”. Leishmaniasis is the most prevalent...

toid, erythematous-vesicular, or urticarial lesions appear on the periphery of and at a distance from the area of the original contact. Histopathology findings are nonspecific. Spongiosis and exocytosis are common findings, although vacuolar degeneration of the basement membrane or epidermal necrolysis is more unusual. Acrylate-induced allergic contact dermatitis usually manifests as eczematous...

BACKGROUND Allergic contact dermatitis caused by rubber gloves is not infrequent, and has almost exclusively been attributed to contact sensitization to accelerators. Thiurams have been the most frequent allergens, followed by dithiocarbamates. OBJECTIVES To describe the current allergen pattern in patients with occupational allergic contact dermatitis caused by rubber gloves. METHODS This ...
